yeah went in easy mate, in the front passenger footwell and laying on the middle plastic part. if your going to pick them up take something to wrap them in as mine weren't wrapped and rattled a bit on the way home.
i just screw in. the skirts are easy enough to get off. i drilled quid guide hole while the skirt and the step were together. the skirt just sits on top and balances quite well. then i drilled 5mm holes, refitted the skirts and bolted the steps on using the original bolts.
